📖 Read the story
Scientists made a new robot. It looks like a small animal called an armadillo. An armadillo has a hard shell. When it is afraid, it rolls into a ball. The new robot does the same thing. At first, the robot is flat. But when someone touches it, it rolls up quickly. The robot has a strong cover. A 3D printer made this cover. It is very strong and protects the machine inside. Scientists made this robot to keep small tools safe. These tools are often fragile. This means they can break easily. Robots often work in dangerous places. For example, they go into deep oceans or hot volcanoes. They can fall or get hit by heavy objects. This hard shell acts like armor. It keeps the tiny machines safe. This is a great way to help robots work in difficult places!
